LIBLTFAT -- Backend library of LTFAT

This is a standalone backend library of LTFAT.

Dependencies

The library depends on FFTW, BLAS and LAPACK. On Ubuntu, just run

sudo apt-get install libfftw3-dev libblas-dev liblapack-dev

followed by

make
sudo make install PREFIX=/usr/local

You might also need to run

sudo ldconfig

to make the just installed library accesible.

Building with MAKE (Linux)

There are three target libraries (static and shared versions)

• build/libltfat.a(.so) Contains double and single prec. versions of the functions
• build/libltfatd.a(.so) Just double prec. versions of the functions
• build/libltfatf.a(.so) Just single prec. versions of the functions

The dependency on BLAS and LAPACK can be disabled by calling

make NOBLASLAPACK=1

The dependency on FFTW can be disabled by calling

make FFTBACKEND=KISS

The internal KISS FFT implementation will be used.

Building with CMAKE (Linux, Windows)

By default, cmake is configured as if NOBLASLAPACK=1 and FFTBACKEND=KISS were set such that libltfat is standalone (except for the libm dependency).

Documentation

Doxygen generated documentation is available here.
